Read Chapter 33: The Heart of the First Flame

The smoke was thinner here, three streets north of where the fire had already eaten its fill. Tom leaned against the crumbling wall of an abandoned cooper's shed, the iron box open on his knees, and cracked the wax seal on his mother's letter. The paper inside was dry, crisp, the ink a faded brown that had not seen light in years.

Alice crouched beside him, watching the lane. She had not spoken much since the crypt. Her hands were still smudged with dust from the fallen church, and there was a cut on her cheek he had not noticed before. She kept looking back toward St. Dunstan's, as if expecting the monk to rise from the smoke and follow.

Tom read.

*My dearest Edmund,*

*If you are reading this, then the box has found its way to you, and I am sorry for it. You were always the clever one, and I have trusted you with more than you know. This is not a pardon. I lied to keep it from Percy's hands. What you hold is the last remaining measure of a substance brought from Constantinople by a man who served the old king's grandfather. They call it Greek Fire.*

Tom stopped. He read the words again. The phial in his hand was heavier than it should have been—a thick glass vessel stoppered with wax, the liquid inside the color of old blood.

"What does it say?" Alice asked.

He did not answer. He read on.

*It burns on water. It burns on stone. It burns where nothing else can burn. The man who brought it said the formula was lost with the fall of their empire, and only one measure remained. My father—your grandfather—kept it hidden for the Crown. When Percy learned of it, he wanted it for himself.*

*Percy does not mean to burn one house or one street. He means to burn the whole of the city, and rebuild it in his own image. With London gone, the King will have no choice but to lean on those who still stand. Percy intends to be the one standing.*

Tom's hands were shaking. He remembered the fire that killed his father—the way it moved, the way it chased him down the street, the way water did nothing but feed it. He had been a boy, and he had watched his father walk into that wall of flame and not come out. He had always blamed the dry summer, the wind, the carelessness of the city. Now he knew better.

Alice touched his arm. "Tom. What is it?"

He folded the letter and pressed it into his coat. "Percy killed our father."

She went still. The blood drained from her face, but she did not look away. "How do you know?"

"Because the fire that killed him wasn't a fire. It was this." He held up the phial, watching the liquid slide against the glass. "Father didn't die in an accident. Percy tested it on him. Or used it to cover the trail, or—I don't know." His voice cracked. "I don't know. But this was there. This was always there."

Alice took the phial from his hand with surprising gentleness. She held it up to the dull orange light filtering through the shed's broken roof. The liquid caught the glow, shimmering like something alive.

"Can it be destroyed?" she asked.

"I don't know." Tom looked down at the open box. There were more papers inside—the map, the letter, a thin roll of parchment tied with red ribbon. He pulled out the ribbon and unrolled it. The script was ornate, a formal hand that spoke of chanceries and clerks.

*By order of His Majesty King Charles II, let it be known that any person who delivers the Sower of Discord, the incendiary responsible for the fires that ravage this city, into the hands of the Crown shall receive a full and unconditional pardon for all crimes committed before this decree, and a sum of one thousand pounds sterling.*

Tom read it twice. Then a third time.

Alice read it over his shoulder. "A pardon," she said. "It *is* a pardon."

"It's a bounty." Tom laughed without humor. "Percy wrote this. He means to pin the fires on someone—probably me—and use the decree to make every man in England hunt for us. The pardon isn't for us. It's for whoever brings him the box."

"Or whoever brings him the Sower."

"Same thing." Tom rolled the parchment tightly. "He's turned the whole country into his own army. He doesn't need to chase us himself. He just needs to wait for someone else to do it."

Alice was quiet for a moment, studying the map spread across the box's open lid. The markings were careful and precise—the Tower, the bridge, the river. Lines crossed between them, connecting church steeples and market squares. She traced one line from a point near the docks to a mark at the heart of the old city.

"This is a plan," she said. "Not for one fire. For a pattern."

"He means to light them all at once." Tom's voice was flat. "Greek Fire in every corner of London. Water won't stop it. Nothing will. The city will burn until there's nothing left to burn."

"Then we destroy the box."

"We can't." He looked at her, helpless. "Not until we're done with it. The pardon—it's signed by the King. It's real. If we can catch Percy, or prove what he's done—"

"Prove it to who? The King is trying to save London. He's not reading petitions from thieves in a burning city."

Tom fell silent. She was right. He hated how often she was right.

The crack of a footstep outside made them both freeze. Tom shoved the phial back into the box and snapped the lid shut, fumbling with the clasp. Alice pressed her back to the wall, eyes fixed on the gap in the shed's door.

A shadow passed across the opening. Then another.

"There was a light," a voice said—low, clipped, familiar. The red-cloaked man. "In the cooper's shed. I saw it from the street."

Tom held his breath. The iron box was cold against his chest, the leather strap digging into his shoulder. He counted the steps—two men, at least, maybe three. They were close enough that he could smell horse and sweat and the oil that men used to keep leather supple in the wet.

"Search the buildings," the red-cloaked man said. "Start with the shed. Burn anything that moves."

Alice's hand found his in the dark. Her grip was strong, deliberate. She did not look afraid—she looked like she was thinking, measuring, deciding.

"The back wall," she whispered. "There's a gap behind the barrel rack."

Tom followed her gaze. The stacked barrels behind them were rotted, half-collapsed, but behind them the shed's timber had pulled away from the frame, leaving a shadowed gap just wide enough for a child or a very thin thief.

Not for Alice. She had grown thin in the chapel, but not that thin.

"Go," she said. "Take the box."

"You first."

"I'm too big. I'll hold them off—"

"No." He pulled her toward the gap. "We both fit. Now."

She did not argue. She twisted sideways through the gap, her ribs scraping against the splintered wood, and Tom pressed the box in front of him, following close enough to feel her hair brush his face. They emerged into an alley no wider than a coffin, brick walls rising on either side, the smoke thick enough to hide a charging army.

Tom pulled Alice along the alley, away from the shed, away from the voices. He did not look back.

But his mind was still open on the map, tracing the lines that connected the city's heart to its veins. Percy's pattern. Percy's fire. And in his chest, the box that carried both salvation and ruin.

He could destroy the Greek Fire. He could empty the phial into the Thames and watch it sink below the dark water, where no spark would ever find it. But the box itself—the papers, the map, the decree—that was all he had to bargain with.

He needed to find Percy. And Percy, no doubt, needed him just as badly.

The thought made him run faster.
